If you want a ready-to-import file with specific tile providers or your own URLs, tell me which providers or URLs to include.
The onlinemapsources.xml file is the configuration engine OruxMaps uses to define and access online tile servers, such as OpenStreetMap or Google Maps. While the app includes an official version, users can create a personalized file to integrate custom WMS (Web Map Service) and WMTS (Web Map Tile Service) layers. Core Structure & Syntax
Each map source is defined within an uid: A unique numerical ID for each map. name: The display name that appears in the OruxMaps menu.
url: The endpoint for tile requests, typically wrapped in a section to handle special characters like &. It uses variables to dynamically fetch tiles: $x, $y: Tile coordinates. $z: Zoom level.
$s: Server cluster (e.g., a,b,c defined in the
minzoom & maxzoom: Defines the zoom range for which the source is active. projection: Usually MERCATORESFERICA for standard web maps.
cacheable & downloadable: Binary flags (0 or 1) that determine if tiles can be saved to the internal cache or used to create full offline maps. Installation & Best Practices
To ensure your custom maps aren't overwritten during app updates, follow these storage guidelines provided by OruxMaps: OruxMaps-Online-Maps/onlinemapsources.xml at master
The onlinemapsources.xml file is the configuration backbone for OruxMaps, a powerful Android-based navigation app designed for outdoor activities like hiking and cycling. This file allows users to define and integrate custom online map sources, such as Google Maps, OpenStreetMap, or specialized Web Map Services (WMS), directly into the application's map viewer. Core Functionality and File Location
By default, OruxMaps includes a standard set of online maps. However, the power of onlinemapsources.xml lies in its customizability. Users can add, remove, or modify map providers to suit their specific regional or activity-based needs.
Primary File: Found at oruxmaps/mapfiles/onlinemapsources.xml.
Custom Maps Directory: To prevent your manual edits from being overwritten during app updates, it is recommended to place personalized XML files in the oruxmaps/mapfiles/customonlinemaps/ folder. XML Structure and Key Tags
The file uses a standard XML format where each map source is wrapped in an uid: A unique identification number for each map.
name: The display name that appears in the OruxMaps "Online Maps" list.
url: The critical entry containing the tile server address, often utilizing variables like $x, $y, and $z to fetch specific map tiles based on coordinates and zoom level.
minzoom & maxzoom: Defines the zoom range the map supports (e.g., 0 to 18).
projection: Specifies the coordinate system, typically MERCATORESFERICA for most web maps.
cacheable: A binary value (0 or 1) determining if tiles should be saved locally for temporary offline use. Integrating Custom Maps Online-maps sources for Orux Maps - AnyGIS
The onlinemapsources.xml file is the configuration backbone for online mapping in OruxMaps, allowing users to integrate various map providers beyond the default list. By modifying or adding this file, you can access satellite imagery, topographic maps, and specialized layers like nautical or weather charts. Core Functionality
Custom Map Integration: It acts as a directory where you define the URL patterns for different map servers. Instead of being limited to built-in options, you can add any source that uses standard tile formats (Google/OSM style), WMS (Web Map Service), or WMTS (Web Map Tile Service).
Persistent Storage: While the app comes with a default file in the oruxmaps/mapfiles/ directory, this file is often overwritten during updates. To keep your custom sources safe, you should place your own version in oruxmaps/mapfiles/customonlinemaps/.
Layer Management: The XML format allows you to specify parameters for each source, including: Min/Max Zoom: Controls the visibility levels of the map.
Cacheable/Downloadable: Determines if tiles can be saved for offline use. Projection: Typically uses MERCATORELIPSOIDAL or WGS84. How to Add New Sources
To expand your map list, you can either manually edit the XML file or download pre-configured files from community contributors:
Download/Edit: Obtain an updated onlinemapsources.xml (popular distributions like AnyGIS offer hundreds of curated sources).
File Placement: Copy the file to the internal storage folder: oruxmaps/mapfiles/customonlinemaps/. Refresh in App: Open OruxMaps and tap the Map icon. Select Switch map > Online.
Tap the Refresh (circular arrows) button to load the new sources from your XML. Creating Offline Maps from Online Sources
A major feature enabled by these XML sources is the ability to create permanent offline maps. Once an online source is active, you can use the "Map Creator" tool to select an area and download specific zoom levels directly to your device for use without a data connection. Sample XML Structure
Each map source is defined within

Recommendations
The onlinemapsources.xml file is the configuration backbone of OruxMaps, a powerful Android navigation tool. It acts as a directory that tells the app exactly where and how to fetch map tiles from various online servers. What is its Purpose?
By default, OruxMaps includes a set of pre-configured maps (like OpenStreetMap). However, users often want access to specialized layers—such as satellite imagery, topographic maps, or weather overlays—that aren't included out of the box. This XML file allows you to manually add these sources by defining their URL patterns, zoom levels, and projection types. Key Components of the File
Each map source within the file is wrapped in an
URL: The template for fetching tiles (e.g., http://openstreetmap.orgz/x/y.png).
Zoom Levels: Defines the minimum and maximum zoom the server supports.
Cacheable: Determines if the app should save tiles locally to save data and allow offline use. How to Customize It
Locate the File: It is usually stored in the oruxmaps/mapfiles/ directory on your Android device.
Edit: You can open it with any text editor. Many users download community-curated versions of this file that come pre-loaded with dozens of regional or specialized map providers.
Refresh: After saving your changes, you must tap the "Refresh" button within the OruxMaps map selection screen to see the new sources. A Note on Usage
While this file is incredibly flexible, it’s important to respect the Terms of Service of map providers. Some servers block high-volume "tile scraping," which can result in your IP being temporarily banned if you try to download massive areas for offline use.

Oruxmaps stores its configuration files in a specific folder structure. The exact path depends on your Android version and whether you have granted storage permissions.
Default location (internal memory):
/Internal Storage/oruxmaps/mapfiles/onlinemapsources.xml
Alternative (older Android versions):
/sdcard/oruxmaps/mapfiles/onlinemapsources.xml
If using scoped storage (Android 11+):
/Android/data/com.orux.oruxmaps/files/mapfiles/onlinemapsources.xml
Cause: Malformed XML – missing closing tag, invalid character, duplicate UID.
Fix: Validate your XML using an online validator (e.g., xmlvalidation.com). Pay special attention to CDATA sections and ampersands (&) which must be written as &.
If you do not see onlinemapsources.xml in the mapfiles directory, Oruxmaps may still be using a default hardcoded list. In that case:
Minimal valid XML template:
